The document discusses different nerve block techniques for anesthetizing specific areas during dental procedures, including the long buccal nerve block, mental nerve block, and incisive nerve block. The long buccal nerve block provides buccal soft tissue anesthesia adjacent to the mandibular molars. The mental nerve block provides sensation to the buccal soft tissue anterior to the mental foramen, lip, and chin. The incisive nerve block anesthetizes the incisive and mental nerves, providing sensation to the mandibular labial mucosa, lower lip, chin, and incisor, canine, and bicuspid teeth.
Mandibular nerve block (other techniques)
- 1. Long Buccal Nerve Block Anterior branch of Mandibular nerve (V3) Provides buccal soft tissue anesthesia adjacent to mandibular molars Not required for most restorative procedures
- 2. Buccal Nerve Block Indications Anesthesia required - mucoperiosteum buccal to mandibular molars Contraindications Infection/inflammation at injection site
- 3. Buccal Nerve Block Advantages Technically easy High success rate Disadvantages Discomfort
- 4. Buccal Nerve Block Alternatives Buccal infiltration Gow-Gates PDL Intraseptal
- 5. Buccal Nerve Block Technique Apply topical Insertion distil and buccal to last molar Target - Long Buccal nerve as it passes anterior border of ramus Insert approx. 2 mm, aspirate Inject 0.3 ml of solution, slowly 25-27 gauge needle Area of insertion:- Mucosa adjacent to most distal
- 6. Buccal Nerve Block Landmarks Mandibular molars Mucobuccal fold
- 7. Buccal Nerve Block Complications Hematoma (unusual) Positive aspiration 0.7 %
- 10. Mental Nerve Block Terminal branch of IAN as it exits mental foramen Provides sensory innervation to buccal soft tissue anterior to mental foramen, lip and chin
- 11. Mental Nerve Block Indication Need for anesthesia in innervated area Contraindication Infection/inflammation at injection site
- 12. Mental Nerve Block Advantages Easy, high success rate Usually atraumatic Disadvantage Hematoma
- 13. Mental Nerve Block Alternatives Local infiltration PDL Intraseptal Inferior alveolar nerve block Gow Gates
- 14. Mental Nerve Block Complications Few Hematoma Positive aspiration 5.7 %
- 19. Incisive Nerve Block Terminal branch of IAN Originates in mental foramen and proceeds anteriorly Good for bilateral anterior anesthesia Not effective for anterior lingual anesthesia
- 20. Incisive Nerve Block Nerves anesthetized Incisive Mental
- 21. Incisive Nerve Block Areas Anesthetized Mandibular labial mucous membranes Lower lip / skin of chin Incisor, cuspid and bicuspid teeth
- 22. Incisive Nerve Block Indication Anesthesia of pulp or tissue required anterior to mental foramen Contraindication Infection/inflammation at injection site
- 23. Incisive Nerve Block Advantages High success rate Pulpal anesthesia w/o lingual anesthesia Disadvantages Lack of lingual or midline anesthesia
- 24. Incisive Nerve Block Complications Hematoma Positive aspiration 5.7 %
